Ultimate Film Strength: Red Line Heavy ShockProof® Gear Oil

For the most extreme protection against gear tooth breakage and shock loads, choose Red Line Heavy ShockProof® Gear Oil (Part #58204), available now at Straight Six Imports. This lubricant is the heaviest of the ShockProof series, engineered for heavily-loaded racing differentials, spools, and non-synchronized transmissions where failure is not an option.

Heavy ShockProof features a unique suspension of solid microscopic particles that act as an extreme pressure cushion. This allows the fluid to maintain a film thickness greater than a conventional 75W250 gear oil, yet retains the low fluid drag and friction of a much lighter 75W90 fluid.

Key Features for Max Drivetrain Protection:

• Unrivaled Load Capacity: Provides an unparalleled "cushion" between gear teeth, drastically reducing metal-to-metal contact and preventing tooth breakage under severe shock loading (e.g., drag launches, high-torque applications).

• Low Drag, High Efficiency: Its low fluid friction reduces drag and heat buildup, leading to lower operating temperatures and maintaining maximum power transfer to the wheels.

• Racing Proven GL-5+: Exceeds API GL-5 specifications and is used across numerous demanding racing applications (NHRA, Sprint/Midget, Dirt Late Model).

• LSD Compatible: Contains the necessary friction modifiers for proper operation in high-performance clutch-type Limited Slip Differentials.

• Synthetic Ester Base: Features superior thermal stability and shear resistance compared to conventional oils, ensuring consistent protection through extended race intervals.

When you require the highest degree of protection for your high-cost racing components, trust the purple difference. Choose Red Line Heavy ShockProof (58204).
